Having aliases for Ethernet devices is useless, since the networking
subsystem unfortunately doesn't care about aliases to name network
interfaces.
Note that the 'aliases' nodes in armada-370-xp.dtsi and armada-xp.dtsi
become empty, but that we keep it as is since a followup patch will
re-add some aliases to it.

The current GPL only licensing on the device tree makes it very
impractical for other software components licensed under another
license.
In order to make it easier for them to reuse our device trees,
relicense our device trees under a GPL/X11 dual-license.

In order to support dynamic frequency scaling:
* the cpuclk Device Tree node needs to be updated to describe a
second set of registers describing the PMU DFS registers.
* the clock-latency property of the CPUs must be filled, otherwise
the ondemand and conservative cpufreq governors refuse to work. The
latency is high because the cost of a frequency transition is quite
high on those CPUs.

Now that mbus has been added to the device tree, it's possible to
move the PCIe nodes out of internal registers, placing it directly
below the mbus. This is a more accurate representation of the
hardware.
Moving the PCIe nodes, we now need to introduce an extra cell to
encode the window target ID and attribute. Since this depends on
the PCIe port, we split the ranges translation entries, to correspond
to each MBus window.

Pull ARM SoC device tree changes from Arnd Bergmann:
"These changes from 30 individual branches for the most part update
device tree files, but there are also a few source code changes that
have crept in this time, usually in order to atomically move over a
driver from using hardcoded data to DT probing.
A number of platforms change their DT files to use the C preprocessor,
which is causing a bit of churn, but that is hopefully only this once"

The length of the registers area for the Marvell 370/XP Ethernet
controller was incorrect in the .dtsi: 0x2400 while it should have
been 0x4000. Until now, this problem wasn't noticed because there was
a large static mapping for all I/Os set up by ->map_io(). But since
we're going to get rid of this static mapping, we need to ensure that
the register areas are properly sized.

Introduce a 'internal-regs' subnode, under which all devices are
moved. This is not really needed for now, but will be for the
mvebu-mbus driver. This generates a lot of code movement since it's
indenting by one more tab all the devices. So it was a good
opportunity to fix all the bad indentation.

The Armada XP SoCs have multiple PCIe interfaces. The MV78230 has 2
PCIe units (one 4x or quad 1x, the other 1x only), the MV78260 has 3
PCIe units (two 4x or quad 1x and one 4x/1x), the MV78460 has 4 PCIe
units (two 4x or quad 1x and two 4x/1x). We therefore add the
necessary Device Tree informations to make those PCIe interfaces
usable.

The SDIO interface is only available on pins MPP30/31/32/33/34/35 on
the various Armada XP variants, so we provide a pin muxing option for
this in the Armada XP .dtsi files.
Even though those muxing options are the same for MV78230, MV78260 and
MV78460, we keep them in each .dtsi file, because the number of pins,
and therefore the declaration of the pinctrl node, is different for
each SoC variant.

The Armada XP GPIO controller has two ways of notifying interrupts:
using global interrupts or using per-CPU interrupts. In an attempt to
use the best available features, the 'marvell,armadaxp-gpio'
compatible string selects a variant of the gpio-mvebu driver that
makes use of the per-CPU interrupts.
Unfortunately, this doesn't work properly in a SMP context, because we
fall into cases where the GPIO interrupt is enabled on CPU X at the
GPIO controller level, but on CPU Y at the interrupt controller
level. It is not yet clear how to fix that easily.
So for 3.8, our approach is to switch to global interrupts for GPIOs,
so that we do not fall into this per-CPU interrupts problem.
This patch therefore fixes GPIO interrupts on Armada XP
platforms. Without this patch, GPIO interrupts simply do not work
reliably, because their proper operation depends on which CPU the code
requesting the interrupt is running.

We originally thought that the MV78230 variant of the Armada XP had
four Ethernet interfaces, like the other variants MV78260 and
MV78460. In fact, this is not true, and the MV78230 has only three
Ethernet interfaces.
So, the definitions of the Ethernet interfaces is now done as follows:
* armada-370-xp.dtsi: definitions of the first two interfaces, that
are common to Armada 370 and Armada XP
* armada-xp.dtsi: definition of the third interface, common to all
Armada XP variants.
* armada-xp-mv78260.dtsi and armada-xp-mv78460.dtsi: definition of
the fourth interface.

The gpioX aliases are needed so that the driver can use
of_alias_get_id() to get a 0-based number of the GPIO bank, which we
then use to compute the base GPIO of the bank being probed. This is
similar to what gpio-mxs.c is doing.

This commits adds the necessary device tree information to define the
compatible property for the pinctrl driver instance of Armada XP SoCs.
Until now, the device tree representation considered the Armada XP as
a single SoC. But in fact, there are three different SoCs in the
Armada XP families, with different number of CPU cores, different
number of Ethernet interfaces... and different number of muxable pins
or functions. We therefore introduce three armada-xp-mv78xx0.dtsi for
the three SoCs of the Armada XP family. The current armada-xp-db.dts
evaluation board uses the MV78460 variant of the SoC.
